Powers and Abilities

Both Upchucks have four very strong, adhesive tongues that can stretch to great lengths, allowing them to latch onto large objects and reel them in with relative ease.

Both Upchucks' mouths can stretch, allowing them to swallow objects larger than themselves. They are connected with a trans-space bladder dimension where they store all the "food" they eat.

By breathing air out of their mouths, both Upchucks are able to fly.

The items ingested are converted into explosive balls of liquids that can be expelled with great accuracy. Perk Upchuck can also make them curve, like a boomerang, shuriken, or frisbee. Murk Upchuck hasn't shown this.

Perk Upchuck is able to take a surprising amount of punishment for a creature of its size, taking the force of a moving car impact as well as surviving after being thrown through a wall.

Both Upchucks can eat and spit out energy, such as lasers, in the same way he eats and spits out acid matter. In Duped, it is shown that Murk Upchuck can spit out slime. Perk Upchuck hasn't displayed this.

In Heroes United, Murk Upchuck was capable of eating Alpha's containment ball, demonstrating to have very strong and durable tongues, as the ball weighed an immeasurable amount.

Weaknesses

Both Upchucks have a limit to how many big objects they can swallow at once.

Both Upchucks are slow when they eat a lot of things and become excessively fat. Otherwise, they are somewhat quick, considering their small size.

If either Upchuck does not spit out something he eats, he will get very fat and rendered immobile until he spits it out.
